Hello this is my first post. I had read several post to try to fix my issue and can't decided where to begin. I have a boost I1 and I downloaded a file manager. For some reason during the download it froze. I waited for 10 mins and decided to pull the battery. Now when I power it on it is suck at the M logo and constantly reboots to this same logo. Plz any ideas I am lost whithout it. P.S. I just pulled my sim and sd card for fear of damaging them. Please help.
